significant figures

For a multiplication or division, you should check how many significant figures each of the factors has, and take the least of them. This is the number of significant figures you should keep in the answer.

If the answer is equal to exactly .500000 do not round. If the answer in below this, then round down and if it is greater then round up.

The molar mass of an element is its atomic weight in grams. The atomic weight is on the periodic table. 1 mole C = 12.0107 g C. To calculate the number of moles in 80 g of C, do the following: 80 g C x (1 mole C/12.0107 g C) = 6.66 mole C = 7 mole C* *This answer has been rounded to the proper number of significant figures. When multiplying or dividing, the answer is rounded to the fewest significant figures used in the calculation. 80 only has one significant figure. Refer to the related link below concerning significant figures.

The rounded value is 10. See also the links below. * * * * * However, there is no such thing as the correct number of significant figures (sf). SF depends on the context as well as the SF of the numbers used to compute the value.

Subscripts are when values in text are put below the normal text, like when specifying bases in mathematics. It is the opposite to superscripting, where values are above the regular text, like st following 1 to specify first. The st is normally smaller and higher than the 1.Subscripts are when values in text are put below the normal text, like when specifying bases in mathematics.

The average z score chart lists z scores with three significant figures. For example, you can find the z score -1.81 on the chart, but not -1.812 or -1.818. In the case that you wish to look up a z score with more than three significant figures, round it to three significant figures and then use the chart. OR You can also use a calculator if you wish to get more accurate results. The link for calculator is mentioned below.

Trailing zeros after a decimal point are not normally written. As trailing zeros have been written they must be significant; thus 101.0100 has 7 sig fig.

When a number is written in scientific notation, the digits that do not appear are not significant. The rest are significant figures. For example, when you convert 0.0003102 to scientific notation, it is 3.102 X 10-4. Therefore the zeros before the 3 are not significant.The 3 significant figures implies to all digits around it, regardless of before and after the decimal point. 8.00 has 3 sig.figs. This is because of the 2 zeroes after the decimal point. When you have 30 zeroes after the decimal point, such as 3.000000000000000000000000000000, you have 31 significant figures. 1.23 has 3 sig.figs. This applies to all questions, if needed.The amount of figures given in an answer where you begin with approximates of numbers. The answers should not be more precise than the original measurements. This would lead to a misleading answer, and thus significant figures were created to show an accurate approximation of your answer.The idea of significant figures (sig figs or sf), also called significant digits (sig digs) is a method of expressing error in measurement.The most significant digit is the "first" digit of a number (the left-most non-zero digit). Similarly, the least significant digit is the "last" digit of a number (sometimes, but not always, the right-most digit). A number is called more significant because it carries more weight. In the decimal number system (base 10), the weight of each digit to the left increases by a multiple of 10, and conversely the weight of each digit to the right decreases by a multiple of 10. A similar thing happens in the binary (base 2) number system - see most significant bit.Sometimes the term "significant figures" is used to describe some rules-of-thumb, known as significance arithmetic, which attempt to indicate the propagation of errors in a scientific experiment or in statistics when perfect accuracy is not attainable or not required. Scientific notation is often used when expressing the significant figures in a number.The concept of significant figures originated from measuring a value and then estimating one degree below the limit of the reading; for example, if an object, measured with a ruler marked in millimeters, is known to be between six and seven millimeters and can be seen to be approximately 2/3 of the way between them, an acceptable measurement for it could be 6.6 mm or 6.7 mm, but not 6.666666... mm as a recurring decimal. This rule is based upon the principle of not implying more precision than can be justified when measurements are taken in this manner. Teachers of engineering courses have been known to deduct points when scoring papers if excessive significant figures are given in a final answer.Each of the digits of a number that are used to express it to the required degree of accuracy, starting from the first nonzero digit.Significant figures (also called significant digits) can also refer to a crude form of error representation based around significant figure rounding.Significant figures are digits that show the number of units in a measurement expressed in decimal notation.

Two. Think of it like this: if you want to compare the population of different cities, you'd want to have the numbers expressed quite roughly, to two or three significant figures. Everybody realises that these numbers would not be an accurate total of all the people there. Any number of people below 544444 would give 540000 when given to two sig figs. More than that would become 550000. If you require more accuracy from your numbers eg if you had to ensure a liferaft space for every person on board a ship, then you need to use more significant figures in your numbers.
